75mm x 30mm Blower Fan Upgrade. I designed this to help cooling when working with Timberfill and Bronzefill filaments, but works really well with PLA and helps with bridging, overhangs or small details which are prone to overhearing. Check out the results on my #3DBenchy Using Fillamentum PLA Extrafill Rapunzel Silver Notes: The Fan duct does not need the classic "notch" because it attached further out allowing more airflow. You can use the duct by itself without the FAN upgrade, simply by fitting the standard fan on the outside of the mount. The shim is designed to replace the space occupied by the standard fan if you which to use another standard size duct. Check Instructions for full details of parts.
